The second encoding discipline was the dynamic conversion of a 200 MB WAV file into MP3 audio format. The Lame 3.90 program, which only supports MMX, was used for this. The program was started with the parameters -v -V 0. This creates an MP3 file with a variable bit rate between 160 kbps and 320 kbps.
As we can see, the Athlon XP 2000+ gave Lame defeat at the audio encoder, after the Pentium 4 2.2 GHz had already caught ominously close. The Pentium 4 can gain no less than 8.5 percent and is thus around 7.5 percent faster than AMD's Athlon XP.
In order not to look at the audio encoding too one-sidedly, the Magic Music Maker was used in this comparison test. Fortunately, the Pentium 4 offers full SS2 support. Here, too, we chose the 200 MB WAV file that Lame already used. In addition to MP3s (high quality, 320 kBit, variable bit rate), we also let the program generate MP3Pro (320 kBit, variable bit rate) files. However, the latter was taken over by a different codec. The following graphics illustrate the small but subtle differences that result when encoding.
After Lame, there is now only one leader in Magic Music Maker. While the Athlon XP was the fastest of its kind with MP3Pro encoding, it can no longer compete with the new Pentium 4 here either. With MP3 encoding, the result is much clearer. The SSE2 support from Magic Music Maker pays off here in particular
